3m™ fiber disc 982c 4-1/2" x 7/8" precision shaped ceramic grain 36+ grit our 3m™ cubitron™ ii fiber disc 982c is well-suited for edge chamfering, beveling, and removing carbon steel welds, mill scale, pits and imperfections, machining grooves, and more. Proprietary cubitron™ ii products have raised the bar for high-performing abrasives. 3m engineers started with 3m™ ceramic abrasive grain and used 3m precision shaped grain technology to generate triangular shaped grains that are electrostatically oriented on the backing to form sharp peaks and maximize cutting potential.
- These peaks act like individual cutting tools that slice through metal, and continuously shelf-sharpen as the points break off
- The grains wear evenly and self-sharpen, reducing heat due to friction for up to twice the life of other fiber discs, with less grinding pressure
- The result is that cubitron™ ii discs outcut and outlast every conventional ceramic industrial abrasive disc on the market, maximizing productivity and minimizing operator fatigue
- Fiber discs are heavy-duty discs ideal for weld removal, grinding, and blending large and small areas of metal surfaces
- They feature a tough, stiff backing made from vulcanized fiber that resist wear and can handle tough grinding applications
- Primary application is metalworking
